Passive damping solution to optical image stabilization for voice control motors

ABSTRACT

Passive dampers (e.g., a viscoelastic material such as a silicon gel) may be applied at one or more locations within an actuator module along wires suspending a moving component (an optics assembly) from a fixed component (e.g., a base of an actuator module). The passive dampers act to passively dampen the motion of the optics assembly on the XY plane within the actuator module during optical image stabilization (OIS) of the optics assembly when subjected to external excitation or disturbance, and may also provide Z (optical) axis damping and impact protection. Process control and automation manufacturing and assembly methods for an OIS voice coil motor (VCM) actuator module including passive dampers are described, as well as design elements that provide for the integrity and reliability of the passive dampers over the life cycle of the actuator module.

BACKGROUND

Technical Field

This disclosure relates generally to control of the motion of camera components.

Description of the Related Art

The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. Some small form factor cameras may incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation or disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens. Some small form factor cameras may incorporate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plane or field in front of the camera at an image plane to be captured by an image sensor (also referred to herein as a photosensor). In some such autofocus mechanisms, the optical lens is moved as a single rigid body along the optical axis (referred to as the Z axis) of the camera to refocus the camera. In addition, high image quality is easier to achieve in small form factor cameras if lens motion along the optical axis is accompanied by minimal parasitic motion in the other degrees of freedom, for example on the X and Y axes orthogonal to the optical (Z) axis of the camera. Thus, some small form factor cameras that include autofocus mechanisms may also incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation or disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens.

SUMMARY OF EMBODIMENTS

An apparatus for controlling motions of an optics component (e.g., a lens or lens system) relative to an image sensor within a camera may include an actuator mechanism for controlling the position of the optics component relative to the image sensor along two axes (X, Y) orthogonal to the optical (Z) axis of the camera. The apparatus may be referred to herein as an actuator module. In some embodiments, an optics assembly that includes the optics component and at least some components of the actuator mechanism may be suspended on a plurality of wires or beams over a base of the actuator module, with the image sensor disposed at or below the base. Each suspension wire may be substantially parallel to the optical axis. In at least some embodiments, the wires are capable of bending deformations that allow the optics assembly to move in linear directions orthogonal to the optical axis (i.e., on the XY plane). The actuator mechanism may provide optical image stabilization (OIS) for the camera, and in some embodiments may be implemented as a voice coil motor (VCM) actuator mechanism. The actuator module may, for example, be used as or in a miniature or small form factor camera suitable for small, mobile multipurpose devices such as cell phones, smartphones, and pad or tablet devices. In at least some embodiments, the actuator module may also include a focusing mechanism for moving the optics component along an optical (Z) axis within the optics assembly.

Embodiments of passive damping techniques for an actuator module that includes an optics assembly are described herein. In embodiments, a passive damping component (e.g., a gel such as a silicon gel, silicone gel (the two terms being used interchangeably herein), or other material) may be applied at one or more locations within the actuator module along the suspension wires. The passive damping components may be referred to herein as passive dampers. In some embodiments, the locations where the passive dampers are applied may be within a magnet holder component of the optics assembly or other component suspended on the plurality of wires from the fixed base component, where the magnet holder component is part of the actuator mechanism.

The application of the passive dampers at these locations, physical properties of the passive damping material (e.g., a silicon gel) such as viscoelasticity, and the contact of the passive dampers with a surface of the moving component (e.g., an optics assembly) and with a surface of the fixed component (e.g., a cover fixed to a base) may act to passively dampen motion of the optics assembly on the XY plane within the actuator module during optical image stabilization (OIS) of the optics assembly when subjected to external excitation or disturbance. In some embodiments, the passive dampers may also provide damping and reduce impact shock on the optics assembly. Further, this location of the passive dampers may be a favorable design for process control and automation during manufacturing and assembly of an OIS VCM actuator module. In addition, at least some embodiments may include design elements that provide for the integrity and reliability of the passive damping material (e.g., damping gel) over the life cycle of the actuator module.

Passive Damping for Optical Image Stabilization

FIGS. 1A and 1B illustrate motion of an optics component 1002 within an actuator module 1000, according to at least some embodiments. As shown in FIG. 1A, an actuator module 1000 may provide optical image stabilization (OIS) for the optics component 1002. In at least some embodiments, the actuator module 1000 may implement a voice coil motor (VCM) actuator mechanism. An actuator module 1000 such as an OIS VCM actuator module may provide motion to optics component 1002 in the XY plane. In addition, in some embodiments, motion may also be provided to optics component 1002 on the Z (optical) axis, for example by a focusing mechanism of the actuator module 1000 for moving the optics component 1002 along the optical (Z) axis within the actuator module 1000. The XY plane motion is, for example, for optical image stabilization (OIS) relative to a photosensor in a camera. The Z axis motion may, for example, be for optical focusing or autofocus purposes in cameras that incorporate focusing/autofocus mechanisms. Example embodiments of an optical image stabilization (OIS) voice coil motor (VCM) actuator are illustrated as actuator module 3000 in FIGS. 4-6. Embodiments of the actuator module 1000 may, for example, be used in a miniature or small form factor camera suitable for small, mobile multipurpose devices such as cell phones, smartphones, and pad or tablet devices, as described below with respect to FIGS. 11-12.

FIG. 1B illustrates components of an example actuator module 1000 that provides X, Y and Z motions for an optics component 1002, according to at least some embodiments. In some embodiments, an optics assembly of the actuator module 1000 may include an optics component 1002 that is coupled to an actuator component 1004 by upper and/or lower springs 1030 and 1032. Note that the object field side of the optics component 1002 may be referred to as the top or upper side or surface of the actuator module 1000 and optics assembly, while the photosensor side of the optics component 1002 may be referred to as the bottom or lower side or surface of the actuator module 1000 and optics assembly. The actuator component 1004 may, for example, include magnets used in a voice coil motor (VCM) actuator mechanism. The springs 1030 and 1032 may be flexible to allow motion of the optics component 1002 on the Z axis relative to the actuator component 1004. The actuator mechanism may be configured to move the optics component 1002 on the Z axis within the actuator module 1000 to provide focusing or autofocus for the camera. The optics assembly, which includes at least optics component 1002, actuator component 1004, and springs 1030 and 1032, may be suspended within the actuator module 1000 on two or more suspension wires 1020. For example, the suspension wires 1020 may be mounted to base 1008, and the optics assembly may be suspended on the wires 1020 at the outer portion of the upper springs 1030. The suspension wires 1020 may be flexible to allow motion of the optics assembly, and thus of the optics component 1002, on the XY axes orthogonal to the Z (optical) axis of the optics component 1002. The actuator component 1002 may be configured to move the optics assembly and thus the optics component 1002 on the XY axes within the actuator module 1000 to provide optical image stabilization (OIS) for the camera.

A challenge with optical image stabilization (OIS) within an actuator module 1000 of a camera is the capacity to control the optics component 1002 and to displace the optics component 1002 accurately back to the optical center relative to the XY plane when subject to external excitation or disturbance. FIG. 2 illustrates instability of an OIS voice coil motor (VCM) actuator under an external excitation or disturbance that is equal to a natural resonant frequency. In at least some embodiments, an OIS VCM actuator mechanism has, by design, specific natural resonant frequency modes noted as F₀, F₁, . . . F_(n). Factors including one or more of structure, material, geometry, assembly, mass, and so on may affect these natural resonant frequency modes. FIG. 2 shows a spike at natural resonant frequency mode F₀. In XY excitation, the first order of natural resonant frequency F₀ for an OIS VCM actuator mechanism is typically low, for instance around 60 Hz.

In terms of controlling the actuator mechanism, it may be difficult to stabilize the optics under an external excitation or disturbance that is equal to a natural resonant frequency of the actuator mechanism, which may limit the performance of the control system for the actuator mechanism. If the system falls into one of these frequencies under an external excitation, the moving component of the actuator module may exhibit higher amplitude of movement, shown as the gain in FIG. 2. As a result, the system may become unstable. When the system becomes unstable, image quality is adversely affected.

In order to improve the stability of systems including but not limited to OIS VCM actuator systems, a solution is to use one or more passive damping techniques. FIG. 3 illustrates stabilization of an OIS VCM actuator under an external excitation or disturbance that is equal to a natural resonant frequency using a passive damping technique, according to at least some embodiments. The dashed line shows how a passive damping technique may smooth the spike at natural resonant frequency mode F₀.

An example passive damping technique involves the application of a non-rigid, viscous and/or elastic (or viscoelastic) substance or material at one or more locations within a system, an example of which is a silicon gel that may be applied at location(s) within the system and activated by the application of UV light. Silicon damping gels have been applied in various systems for improving stability and increasing control performance. However, note that other gels, substances, materials, and/or mechanisms may be used in various passive damping techniques.

FIGS. 4-6 illustrate embodiments of an example actuator module in which embodiments of a passive damping techniques as described herein may be applied. In particular, embodiments of the passive damping techniques may be applied within an actuator module 3000 as illustrated in FIGS. 4-6 to stabilize and increase control performance during optical image stabilization (OIS) of an optics assembly 3060 suspended on wires 3020 within an actuator module 3000 as shown in FIG. 4.

Cover 3012 may be attached to the base 3008, substantially enclosing the optics assembly 3060 while leaving an aperture to allow light from an object field in front of the camera module 3000 to reach the optics component 3002 and leaving an opening in base 3008 to allow light refracted from optics component 3002 to reach the image sensor 3050. Base 3008 may include one or more of, but is not limited to a ceramic substrate, to which is attached one or more magnet displacement sensors 3010, and suspension wires 3020 around which are disposed passive dampers 3040. In at least some embodiments, there are four suspension wires 3020. An optics assembly 3002 may be suspended on the base 3008 by suspension of the upper springs 3030 of optics assembly 3002 on the suspension wires 3020. Camera module 3000 may include one or more of, but is not limited to, optics component 3002, optics holder 3004, magnet holder(s) 3006, upper spring(s) 3030, and lower spring(s) 3032. The upper and lower spring(s) may be collectively referred to herein as optics springs. In actuator module 4000, an optics component 3002 (e.g., a lens or lens assembly) may be screwed, mounted or otherwise held in or by an optics holder 3004. In at least some embodiments, the optics component 3002/optics holder 3004 assembly may be suspended from or attached to the magnet holder 3006 by upper spring(s) 3030, and lower spring(s) 3032. Note that upper spring(s) 3030 and lower spring(s) 3032 are flexible to allow the actuator assembly 3060 a range of motion along the Z (optical) axis for optical focusing, and wires 3020 are flexible to allow a range of motion on the XY plane orthogonal to the optical axis for optical image stabilization.

One of skill in the art will readily comprehend in light of having read the present disclosure that, in some embodiments, an actuator module 4000 of camera module 3000 may not include magnets and magnet holder(s) 3006, but may include a yoke or other structure that may be used to help support the optics assembly 3060 on suspension wires 3020 via upper sprigs 3030. Such embodiments do not depart from the scope of the present disclosure. However in some embodiments, actuator module 4000 may not include some elements and may include some others not described herein for the sake of simplicity in illustration. In general, other embodiments of an actuator module 4000 may include fewer or more components than the example actuator module 4000 shown in FIGS. 4-5.

In FIG. 5, base 3008 and suspension wires 3020 with passive dampers 3040 are shown in FIG. 5, while optics 3002, optics holder 3004, magnet holders 3006, lower optics spring 3032, and upper optics spring 3030 are also shown. The cover 3012 is not shown in FIG. 5. FIG. 5 shows example locations for four suspension wires 3020 and corresponding dampers at through-holes drilled near the corners magnet holders 3006 of the actuator module 4000, an example location/configuration of upper optics springs 3030 that suspend optics assembly 3060 on suspension wires 3020 and to which magnet holder(s) and optics holder 3004 are attached and thus suspended, and an example location/configuration of lower optics spring 3032 attached to the bottoms or lower surfaces of magnet holder(s) and optics holder 3004. Note that more or fewer suspension wires 3020 may be used in some embodiments.

In the example configuration shown in FIG. 5, four separate magnet holders 3006 are shown disposed around optics holder 3004, each attached to optics springs 3030 and 3032, and each typically holding one of four magnets used in the example actuator module 3000. FIG. 6 shows an alternative configuration for a magnet holder or yoke in a camera module 3000. FIG. 6 shows an embodiment in which suspension wires pass through an open u-cavity in magnet holders 3006 for housing passive dampers 3040, each holding two magnets, with one magnet holder 3006 located on each side of optics holder 3004.

In embodiments of passive damping techniques for an actuator module as described herein, referring to FIGS. 4-5 the locations where the passive damping gel (or other passive damper) is applied is/are disposed around the suspension wires of the moving assembly (the actuator assembly 4000).

The location of the passive damping material 3040 at locations disposed around the plurality of wires 3020, in some embodiments, adjusted to a location favorable for process control and automation during manufacturing and assembly of a camera module 3000, as illustrated in FIGS. 7-10. In addition, at least some embodiments may include design elements that provide for the integrity and reliability of the damping gel over the life cycle of the camera module 3000.

However, it is to be noted that passive dampers as described herein may be applied at one or more other locations within an actuator module 3000 instead of or in addition to locations disposed around suspension wires 3020. For example, in some embodiments, instead of or in addition to locating passive dampers disposed around suspension wires 3020, additional passive dampers may be located at the top of the optics assembly 4000 between the optics assembly 3060 and the cover 3012 of the actuator module 3000, or passive dampers may be located at the bottom of the optics assembly 3060 between the optics assembly 3060 and the base 3008 of the camera module 3000. For example, in some embodiments, the locations where the passive dampers 3040 are applied may be between a magnet holder 3006 component of the actuator module 4000 and magnet displacement sensors 3010 attached to base 3008.

FIGS. 4-6 show embodiments of passive damping components, mechanisms, or materials 3040 (e.g., a damping gel such as a silicon or silicone damping gel), as applied according to at least some embodiments, but are intended to be merely examples and not limiting of the information presented in the present disclosure. For simplicity, each passive damping component in the module 3000 may be referred to as a passive damper 3040. In at least some embodiments, each passive damper 3040 may be an application of a silicon damping gel that may, for example, be cured by application of UV light. However, note that other gels, materials, substances, or mechanisms may be used as passive dampers 3040 at the locations shown in FIGS. 4-6 instead of or in addition to silicon damping gel dampers 3040.

The application or disposition of passive dampers 3040 at these locations, physical properties of the passive damper 3040 material (e.g., a silicon gel) such as viscosity and/or elasticity (viscoelasticity), and the contact of the passive dampers with a surface of the moving component (optics assembly 3060) and with wires 3020 act to passively dampen the motion of optics assembly 3060 during optical image stabilization (OIS) of the optics assembly 3060 when subjected to external excitation or disturbance.

In some embodiments, in addition to damping motion the passive dampers 3040 (e.g., damping gel) disposed around wires 3020 may also act as a damper or “shock absorber,” which may improve reliability, damping acceleration and reducing impact shock of the optics assembly 3060 within the actuator module 3000.

In addition, the location of the passive dampers disposed about the suspension wires 3020 of the optics assembly 3060 may be a favorable location for process control and automation during manufacturing and assembly of an actuator module 4000. In addition, at least some embodiments may include design elements that provide for the integrity and reliability of the passive dampers 3040 over the life cycle of the actuator module 3000.

However, as previously noted, passive dampers 3040 may be applied at one or more other locations within an actuator module 3000 instead of or in addition to locations disposed about the plurality of wires 3020 of optics assembly 3060.

Applying the passive dampers 3040 disposed about the plurality of wires 3020 of the actuator module 4000 may improve the level of damping performance and damping ratio (Q factor) as the relative motion between the moving and static parts reduces significantly. Note that this may impact gel volume, as less gel may be used to provide a target Q damping ratio. As a result, this may improve the manufacturability, dispense and cycle time.

By locating the passive dampers 3040 within optics assembly 3060, the damping gel is further away from temperature sources such as the image sensor 3050 (e.g., a CMOS or CCD photosensor) and the voice coil motor (VCM) coils which may typically be located in or on base 3008. This may act to improve damping performance by reducing variation of the viscoelastic or other properties of the material (e.g., silicon gel) related to temperature.

By locating the passive dampers 3040 within optics assembly 3060, the damping gel can easily be dispensed during manufacturing and assembly of an actuator module 4000, since the passive damping is applied at an accessible location. The actuator module 4000 assembly process can be very specific, but typically the EMI shield can (cover 3012) is mounted last. In addition, this allows for improved process control and automation when applying the passive damping. Thus, this location of the passive damping material on top of the optics assembly 4000 may be a favorable design for process control and automation during manufacturing and assembly of an OIS VCM actuator module. An example manufacturing and assembly process is illustrated in FIGS. 7A through 8E.

Passive Damper Integrity and Reliability

At least some embodiments may include design elements that provide for the integrity and reliability of the passive damping material (e.g., damping gel) over the life cycle of the actuator module 4000. Thus, at least some embodiments may deposit each passive damper 3040 material at or in a site such as pocket, step, cavity, indentation, etc. within a component of optics assembly 3060 that may act to contain the passive damper 3040 material and help prevent the material from squeezing out or spreading too much during displacement events. Note that the size (L×W×H) and/or shape of the pocket may be designed in accordance with the volume of the passive damper 3040 (e.g., damping gel) material. In other words, the pocket may be designed with a size and shape that can accommodate most or all of the passive damper 3040 (e.g., damping gel) material during a displacement.

Manufacturing, Process Control, and Automation Methods

FIGS. 7A through 7E graphically illustrate an example manufacturing process for an actuator module 4000 as shown in FIG. 5 that may be used in a small form factor camera 3000, according to at least some embodiments, and is not intended to be limiting. The process is shown at a high level, with five major stages or steps shown in FIGS. 7A through 7E. FIG. 9 is a flowchart of a method for manufacturing an actuator module 4000 that may be used in a small form factor camera 3000, according to at least some embodiments.

As shown in FIG. 7A and at 3200 of FIG. 9, a base assembly 3008 for an actuator module 4000 is assembled. An example base assembly 3008 is shown in FIG. 4. However, the suspension wires 3020 may not initially be attached to the base assembly 3008.

As shown in FIG. 7B and at 3210 of FIG. 15, an optics assembly is assembled. An example optics assembly 4000 is shown in FIG. 5. Note that the manufacturing steps represented in FIGS. 7A and 7B and at 3200 and 3210 of FIG. 15 may be performed substantially in parallel, e.g. on separate production lines that merge at FIG. 7C.

As shown in FIG. 7C and at 3220 of FIG. 9, the optics assembly (e.g., an optics assembly 3060) may be suspended on/attached to the base assembly (e.g., base assembly 3008) via suspension wires 3020, e.g., four wires or beams disposed at the corners of the base. In at least some embodiments, the optics assembly is suspended on the wires 3020 via upper optics spring 3030 components of the actuator module 4000. The wires 3020 may provide motion to the optics assembly 3060 on the XY plane for optical image stabilization (OIS).

As shown in FIG. 7D and at 3230 of FIG. 9, the passive damping material (e.g., a damping gel such as a silicon gel) is deposited at locations disposed around the suspension wires 3020. FIGS. 8A through 8D graphically illustrate an example method for passive damper 3040 (e.g., damping gel) material application as shown in FIG. 7D. FIG. 10 provides an example of a manufacturing method that may be performed at 3230 of FIG. 9 to apply damping gel at locations disposed around the suspension wires 3020 of an optics assembly 3060.

As shown in FIG. 7E and at 3240 of FIG. 9, a cover (e.g., a cover 3012 with an opening for the optics component 3002 as shown in FIG. 5) may be attached to the base assembly 3008, substantially enclosing the optics assembly 3060 while leaving an aperture in cover 3012 to allow light from an object field in front of the camera module 3000 to reach the optics component 3002 and leaving an opening in base assembly 3008 to allow light refracted from optics component 3002 to reach the image sensor 3050. The cover 3012 and base assembly 3008 form a fixed or static portion of the actuator module 4000, while the optics assembly 3060 is a moving portion of the actuator module 4000.

The application of the passive dampers 3040 at these locations, physical properties of the passive damper 3040 material (e.g., a silicon gel) such as viscoelasticity, and the contact of the passive dampers with a surface of the moving component (optics assembly 3060) and with a surface of the wires 3020 dampen the motion of optics assembly 3060 within the actuator module 4000 during optical image stabilization (OIS) of the optics assembly 3060 when subjected to external excitation or disturbance, and may also provide damping and reduce impact shock for the optics assembly 3060.

FIGS. 8A through 8D graphically illustrate an example method for passive damping material (e.g., a damping gel such as a silicon gel) application as shown at FIG. 7D and at 3230 of FIG. 9, according to at least some embodiments, and is not intended to be limiting. The method may involve one or more of, but is not limited to, four stages or steps as shown as FIGS. 8A through 8D. FIG. 10 is a flowchart of a method for passive damping material application at element 3230 of the method shown in FIG. 9, according to at least some embodiments, and is not intended to be limiting.

As shown in FIG. 8A and at 3232 of FIG. 10, the passive damper 3040 material (e.g., a silicon damping gel) is dispensed to one or more locations on the upper surface of an optics assembly 3060 as described herein.

As shown in FIG. 8B and at 3234 of FIG. 10, a vertical automated optical inspection (AOI) may be performed to determine if the passive damper 3040 material is properly positioned at locations disposed around the suspension wires 3020, and to determine that the extent of the material that was dispensed is within minimum and maximum boundaries. Note that this boundary check may also check the volume of damping material that was deposited.

As shown in FIG. 8C and at 3236 of FIG. 10, the passive damper 3040 material may be cured. For example, a silicon damping gel may be cured via the application of ultraviolet (UV) light by a UV light source at a distance d from the optics assembly surface.

As shown at in FIG. 8D and at 3238 of FIG. 10, an automated optical inspection (AOI) profile scan may be performed to determine if the passive damper 3040 material as cured at FIG. 8C and 3236 of FIG. 18 is within a height H tolerance and within a diameter D tolerance withinoptics assembly 3060.

Attention is now directed toward embodiments of portable devices with cameras. FIG. 11 is a block diagram illustrating portable multifunction device 100 with camera 164 in accordance with some embodiments. Camera 164 is sometimes called an “optical sensor” for convenience, and may also be known as or called an optical sensor system.

Device 100 may include one or more optical sensors 164. These components may communicate over one or more communication buses or signal lines 103.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of the components. The various components shown in FIG. 27 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 102 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU 120 and the peripherals interface 118, may be controlled by memory controller 122.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU 120, and memory controller 122 may be implemented on a single chip, such as chip 104. In some other embodiments, they may be implemented on separate chips.

RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 108 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 108 may communicate with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data may be retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch screen 112 and other input control devices 116, to peripherals interface 118. I/O subsystem 106 may include display controller 156 and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input control devices 116 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternative embodiments, input controller(s) 160 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) may include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons may include a push button (e.g., 206, FIG. 2).

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 112. In an example embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 112 and display controller 156 may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an example embodiment, projected mutual capacitance sensing technology may be used.

Touch screen 112 may have a video resolution in excess of 100 dots per inch (dpi). In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 may also include one or more optical sensors or cameras 164. FIG. 27 shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other videoconference participants on the touch screen display.

Device 100 may also include one or more proximity sensors 166. FIG. 27 shows proximity sensor 166 coupled to peripherals interface 118. Alternatively, proximity sensor 166 may be coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 includes one or more orientation sensors 168. In some embodiments, the one or more orientation sensors include one or more accelerometers (e.g., one or more linear accelerometers and/or one or more rotational accelerometers). In some embodiments, the one or more orientation sensors include one or more gyroscopes. In some embodiments, the one or more orientation sensors include one or more magnetometers. In some embodiments, the one or more orientation sensors include one or more of global positioning system (GPS), Global Navigation Satellite System (GLONASS), and/or other global navigation system receivers. The GPS, GLONASS, and/or other global navigation system receivers may be used for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100. In some embodiments, the one or more orientation sensors include any combination of orientation/rotation sensors. FIG. 11 shows the one or more orientation sensors 168 coupled to peripherals interface 118. Alternatively, the one or more orientation sensors 168 may be coupled to an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more orientation sensors.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, arbiter module 157 and applications (or sets of instructions) 136. Furthermore, in some embodiments memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.).

Contact/motion module 130 may detect contact with touch screen 112 (in conjunction with display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the intensity of graphics that are displayed.
